symfony - Symfony2 - Instantiation of arguments in Services -

i'm having bit of issue , don't know if i'm being stupid, on imaginative, or if didn't quite grasp of services.

say have service defined followed :

awesome:     class: "\\my\\bundle\\services\\awesome"     arguments:         fantabulous: @fanta.bulous #which refers \\another\\bundle\\services\\fantabulous 

say have controller testcontroller in have following action

public function someaction() {     $awesome = $this->get('awesome');     $awesome->dosomething(); } 

say fantabulous class looks :

class fantabulous {     protected $number;      public function __construct($anynumber)     {         $this->number = $anynumber;     }      public function printnumber()     {         return $this->number;     } } 

say awesome service looks :

class awesome {     protected $fantabulous;      public function __construct(fantabulous $fantabulous)     {         $this->fantabulous = $fantabulous;     }      public function dosomething()     {         echo $this->fantabulous->printnumber();     } } 

my question : how pass number (e.g. 14) initialize fantabulous, testcontroller? i've been searching high , low answer couldn't find one, seems me never instatiate in services.

thanks.

you can't! not in case. cannot call service service container , pass arguments @ same time. however, can follow these approaches:

1. add setter method fantabulous (maybe fantabulous::setnumber()) , turn optional $anynumber argument (on construct);
2. create objects on hand rather call container;
3. create factory service in order create "awesome" or others services;

what want has been discussed once project repository, might want take , find out why suggestion not approved. helpful links:

• using factory create services
• [rfc][2.2][dic] specify service constructor parameters code #4142
